Bal-Core
Rare WorkerBal-Core is a Rare Worker droid in Star Wars: Droid Tycoon. Full buy cost, sell value, credits-per-second, and rebirth requirements at every variant.
Variants & economy
Buy / craft cost, the chips to upgrade into each tier, earnings, and what it sells back for. Sell chips double with BB-8 equipped.
| Variant | Buy / craft | Upgrade | Earns | Sell (credits) | Sell (chips) |
|---|---|---|---|---|---|
| Default | 43k | — | 23/s | 30.1k | — |
| Gold | 172k | 30 chips | 46/s | 120k | 6 |
| Diamond | 344k | 50 chips | 92/s | 241k | 9 |
| Rainbow | 516k | 75 chips | 184/s | 361k | 12 |
| Beskar | 688k | 250 chips | 276/s | 482k | 15 |
Each tier doubles the last; Beskar breaks the pattern (×1.5 over Rainbow for Commons/Rares, ×4.25 for Epics, ×3 for Legendaries). Credit sell value is ~70% of buy cost. Buy prices apply on the trade row — including Beskar, which can't be bought anywhere else. Numbers reflect the current balance patch.
Note: Rare Rainbow prices follow a ×12-of-Default pattern confirmed in-game (ID10 and Mouse trade-row reads) — the community tracker mistakenly lists the ×16 Beskar cost there. Rare values are derived from that pattern and not yet read in-game — corrections land same-day.
Specialist placement
Bal-Core is a Worker droid — put it to work in the Worker area for a free +10% to its credits. Most players leave droids scattered in the wrong sections and quietly lose that bonus.
Rebirth requirements
Since the June 9 update, requirements cycle through four paths, one per Super Rebirth (dev-confirmed: 1→2→3→4, then repeat) — all four are now mapped. Listed variant or higher — a higher variant always satisfies a lower-variant requirement.
Path 1 — first run
Path 2 — after 1st Super Rebirth
Path 3 — after 2nd Super Rebirth
Path 4 — after 3rd Super Rebirth
Tip: the highest variant asked for across all four paths is Rainbow. Get Bal-Core to that tier once and every requirement is covered for good.
